## string
|
|
|
|
The `string` module automatically imports the `err` module.
|
|
|
|
#### `byte strzlen(pointer str)`
|
|
|
|
Calculates the length of a null-terminated string.
|
|
If the string is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
#### `sbyte strzcmp(pointer str1, pointer str2)`
|
|
|
|
Compares two null-terminated strings. Returns 0 if equal, non-0 if not equal.
|
|
If any of the strings is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
#### `void strzcopy(pointer dest, pointer src)`
|
|
|
|
Copies the source null-terminated string into the destination buffer.
|
|
If the source string is longer than 255 bytes, then the behaviour is undefined (might even crash).
|
|
|
|
#### `word strz2word(pointer str)`
|
|
|
|
Converts a null-terminated string to a number.
|
|
Sets `errno`.
|
|
|
|
#### `void strzappend(pointer buffer, pointer str)`
|
|
#### `void strzappendchar(pointer buffer, byte char)`
|
|
|
|
Modifies the given null-terminated buffer by appending a null-terminated string or a single character respectively.
